There’s no doubt that AI tools can make your day-to-day easier. But when it comes to trying new tools, you gamble by investing a few hours in trying to set up something that may not work as it claims.
Sometimes, it’s best to keep it simple and stick to the tried-and-tested resources.
ChatGPT, Gemini, Claude, and Microsoft Copilot have been around for a while, and most B2B sales teams will have tried at least one. But while they’re often mentioned in the same breath, they aren’t interchangeable. They’re all powered by large language models (LLMs), yet each has different strengths when it comes to sales tasks.
We outline the benefits and challenges of each tool, and help illustrate their potential by suggesting some of the kinds of sales tasks they could help with.
ChatGPT: The Most Flexible Tool for Sales Messaging
ChatGPT is usually the first AI tool sales reps try, and so it becomes the most used. That’s perhaps its biggest strength: it’s easy and flexible to use. ChatGPT is designed to handle open-ended thinking, writing, and refinement, which maps closely to the day-to-day reality of selling.
For sales reps, this means ChatGPT is particularly strong at shaping language. You can start with a rough idea, such as an awkward email draft, messy call notes, or a half-formed objection response, and refine it step by step with this AI tool. It responds well to feedback like “make this shorter,” “sound more direct,” or “rewrite this for a CFO instead of a technical buyer.”
The trade-off is that ChatGPT doesn’t automatically know anything about your accounts, inbox, or CRM: it only works with the context you give it. When used well, that’s not a major limitation. But it does mean you should consider ChatGPT a thinking partner, rather than a fully automated sales assistant.
ChatGPT is best suited to sales tasks like:
-
Writing cold and warm outreach emails
-
Creating follow-ups after no response
-
Generating discovery questions
-
Handling objections and pushback
-
Turning rough notes into polished recap emails
Gemini: Strong for Research and Account Context
Gemini is less about persuasion and more about understanding. Where ChatGPT excels at writing, Gemini tends to perform best when a sales rep needs context, especially early in the sales process.
For example, Gemini is particularly useful when you’re preparing for a first conversation with a new account or entering an unfamiliar industry. It’s good at synthesising information, explaining how a business operates, and summarising trends or challenges within a sector. Rather than helping you write the perfect email, it helps you understand what matters before you write it.
But the downside is that Gemini is generally less effective for tone-sensitive sales copy. It can help you get informed quickly, but most reps still prefer a different tool when it comes time to craft outreach or follow-ups.
Gemini is best suited to sales tasks like:
-
Researching target accounts or industries
-
Preparing for first discovery calls
-
Understanding competitive or market context
-
Summarising long articles or thought leadership
-
Sense-checking assumptions before outreach
Claude: Best for Summarising and Making Sense of Complexity
Claude stands out when the problem isn’t writing or research, but information overload. It’s particularly effective at working through long, complex, or messy inputs and turning them into something clear and structured.
For sales reps, this often shows up later in the deal cycle, with long call transcripts, dense email threads, procurement documents, or RFPs. Claude handles large volumes of text calmly and reliably, without losing key details or jumping to exaggerated conclusions.
But the trade-off is tone. Claude tends to be more neutral and cautious, which makes it less suitable for punchy outreach or persuasive messaging. Where it shines is clarity, not creativity.
Claude is best suited to sales tasks like:
-
Summarising call transcripts and meetings
-
Extracting objections and next steps
-
Reviewing RFPs or procurement emails
-
Pulling action items from long email threads
-
Creating internal deal summaries for managers
Microsoft Copilot: AI Embedded in Your Daily Workflow
Microsoft Copilot works differently from the other tools because it lives inside Microsoft applications rather than alongside them. For sales teams already using Outlook, Teams, Word, and Excel, this can make Copilot feel less like “using AI” and more like a natural extension of existing workflows.
Its biggest advantage is context. Copilot can draft emails based on real email threads, summarise Teams meetings automatically, and help analyse pipeline data directly in Excel. There’s no need to copy and paste information into another tool, because the AI already sits where the work happens.
However, Copilot is less opinionated from a sales perspective. It’s designed to support productivity inside Microsoft tools, not to coach messaging, prospecting strategy, or objection handling. It’s also typically tied to Microsoft 365 licensing, which may limit access for individual reps.
Copilot is best suited to sales tasks like:
-
Drafting or polishing emails in Outlook
-
Summarising Teams meetings and calls
-
Turning notes into internal documents
-
Reviewing pipeline or forecast data in Excel
-
Creating proposals or decks in Word and PowerPoint
